A vivid urban cartoon graffiti of a whimsical blue puffer fish with striking emerald green eyes, adorned with a tiny spray paint can under one fin, embellishing a brick wall in a gritty New York City alleyway, stylized in the manner of Banksy's iconic street art, blending sharp lines with subtle textures in a 16:9 composition, echoing social commentary through an undercurrent of playful rebellion, merging the charm of marine life with the urban edge of the city's bustling backdrop.
